Question

我正在从PgAdmin4运行一个SQL查询，该查询成功运行，但是当我从Spring Boot应用程序中使用该查询来运行它时，出现错误“ org.postgresql.util.PSQLException：错误：语法错误在或附近“：”“

这是SQL查询的样子：

SELECT
   student.surname, student.first_name, student.last_name,
   jsonb_pretty(elems)
FROM assessment, jsonb_array_elements(assessment.assessment) AS elems
JOIN student ON student.id = (elems->>'student_id')::uuid
WHERE subject_id = 2
AND academy_year_id =3
AND form_id = 2
AND term_id = 1
AND section_id = 4;

此操作从PgAdmin4成功运行。

这是我在存储库中的实现

@Query(nativeQuery = true, value = "SELECT\n" +
        "       student.surname, student.first_name, student.last_name,\n" +
        "       jsonb_pretty(elems)\n" +
        "FROM assessment, jsonb_array_elements(assessment.assessment) AS elems\n" +
        "JOIN student ON student.id = (elems->>'student_id')::uuid\n" +
        "WHERE subject_id = 2\n" +
        "AND academy_year_id =3\n" +
        "AND form_id = 2\n" +
        "  AND term_id = 1\n" +
        "AND section_id = 4;")
Object[] getSubjectAssessments();

当我的API调用此方法时，我会收到此错误消息

org.postgresql.util.PSQLException: ERROR: syntax error at or near ":"

我不知道我在做什么错。

JPA无法处理Postgres专用的强制转换运算符cast()。

改为使用JOIN student ON student.id = cast(elems->>'student_id' as uuid)：

 public static void switchToIFramesOfSearchPage() {
    wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.cssSelector(GENERAL_IFRAME_CSS_LOCATOR_VALUE)));
    driver.switchTo().frame(SEARCH_PAGE_IFRAME1_ID_LOCATOR_VALUE);
    driver.switchTo().frame(SEARCH_PAGE_IFRAME2_ID_LOCATOR_VALUE);
